Section 2.2. Interest. Each Deposit shall bear interest from and including the date of deposit to but excluding the date of withdrawal (it being understood that the date of withdrawal in the case of any payment by the Depositary of the amount of the Final Withdrawal (as defined below) on the Outside Termination Date (as defined below) shall be deemed to be the date of such payment) at the rate of 5.625% per annum (computed on the basis of a 360-day year of twelve 30-day months) payable to the Paying Agent on behalf of the Escrow Agent in arrears on each Interest Payment Date (as defined below), on the date of any Final Withdrawal, on the date of any Replacement Withdrawal (as defined below) or on the date of any Event of Loss Withdrawal (as defined below), as applicable, all in accordance with the terms of this Agreement. As used in this Agreement, the term “Interest Payment Date”, with respect to each Deposit that, as of any date of determination, has not been withdrawn pursuant to a Final Withdrawal, a Replacement Withdrawal or an Event of Loss Withdrawal, shall mean each of July 15 and January 15, commencing on July 15, 2013 and ending on the earlier of July 15 and January 15 immediately following the date on which such Deposit is withdrawn pursuant to a Notice of Purchase Withdrawal (as defined below); provided that interest accrued on any Deposit that is withdrawn pursuant to a Notice of Purchase Withdrawal shall be paid on the next Interest Payment Date following the related Purchase Withdrawal, notwithstanding any intervening Final Withdrawal or Event of Loss Withdrawal with respect to any other Deposit and notwithstanding the fact that the relevant Account may have been closed before such Interest Payment Date, but, if any intervening Replacement Withdrawal occurs before such next Interest Payment Date, such accrued interest shall, instead, be paid on the date of such Replacement Withdrawal.

(c) Compliance with Withdrawal Notices. If the Depositary receives a duly completed Notice of Purchase Withdrawal, Notice of Final Withdrawal, Notice of Replacement Withdrawal or Notice of Event of Loss Withdrawal (each, a “Withdrawal Notice”) complying with the provisions of this Agreement, it shall make the payments specified therein in accordance with the provisions of this Agreement. Notwithstanding anything to the contrary contained in this Agreement, in no event shall the Depositary be required, pursuant to any Withdrawal Notice or otherwise, to make payments hereunder on or in respect of any Deposit in excess of the amount of such Deposit together with accrued interest thereon as provided in this Agreement.

Section 2.4. Other Accounts. On the date of withdrawal of any Deposit (other than the date of any Final Withdrawal, Replacement Withdrawal or Event of Loss Withdrawal), the Escrow Agent, or the Pass Through Trustee on behalf of the Escrow Agent, shall re-deposit with the Depositary any portion thereof not used to acquire Equipment Notes and the Depositary shall accept the same for deposit hereunder. Any sums so received for deposit shall be established as a new Deposit and credited to a new Account, all as more fully provided in Section 2.1 hereof, and thereafter the provisions of this Agreement shall apply thereto as fully and with the same force and effect as if such Deposit had been established on the Deposit Date except that such Deposit may not be withdrawn prior to the date seven days after the establishment thereof. The Depositary may waive the foregoing requirement that any Deposit can only be withdrawn on or after seven days after the establishment thereof, and may instead reserve the right, upon at least 14 days’ prior written notice to American, the Escrow Agent and the Pass Through Trustee, to require seven days’ notice for any withdrawal.

SECTION 3. Termination. This Agreement shall terminate on the fifth Business Day after the later of the date on which (i) all of the Deposits shall have been withdrawn and paid as provided herein without any re-deposit and (ii) all accrued and unpaid interest on the Deposits shall have been paid as provided herein, but in no event prior to the date on which the Depositary shall have performed in full its obligations hereunder.

SECTION 4. Payments. All payments made by the Depositary hereunder shall be paid in United States Dollars and immediately available funds by wire transfer (i) in the cases of (w) accrued and unpaid interest on the Deposits payable under Section 2.2 hereof, (x) any Final Withdrawal, (y) any Event of Loss Withdrawal or (z) accrued and unpaid interest on all Deposits, if any, previously withdrawn pursuant to a Notice of Purchase Withdrawal, which interest is payable pursuant to a Notice of Replacement Withdrawal, directly to the Paying Agent at [        ], or to such other account as the Paying Agent may direct from time to time in writing to the Depositary and the Escrow Agent, (ii) in the case of any withdrawal of one or more Deposits pursuant to a Notice of Purchase Withdrawal, directly to or as directed by the Pass Through Trustee as specified and in the manner provided in such Notice of Purchase Withdrawal, and (iii) the case of any withdrawal of one or more Deposits then held by the Depositary together with accrued and unpaid interest on such Deposits pursuant to a Notice of Replacement Withdrawal, as directed by the Pass Through Trustee as specified and in the manner provided in such Notice of Replacement Withdrawal.

permitted by applicable law, all payments on or in respect of each Deposit shall be made free and clear of and without reduction for or on account of any and all taxes, levies or other impositions or charges (collectively, “Taxes”). However, if the Depositary or the Paying Agent (pursuant to Section 2.04 of the Escrow and Paying Agent Agreement) shall be required by law to deduct or withhold any Taxes from or in respect of any sum payable hereunder, the Depositary shall (i) make such deduction or withholding, (ii) pay the full amount deducted or withheld (including in respect of such additional amounts) to the competent taxation authority and (iii) if the Taxes required to be deducted or withheld are imposed by France, or any political subdivision thereof, pay such additional amounts as may be necessary in order that the actual amount received by the designated recipient of such sum under this Agreement or the Escrow and Paying Agent Agreement after such deduction or withholding equals the sum it would have received had no such deduction or withholding been required. If the date on which any payment due on any Deposit would otherwise fall on a day which is not a Business Day, such payment shall be made on the next succeeding Business Day, and no additional interest shall accrue in respect of such extension.

SECTION 5. Representation and Warranties. The Depositary hereby represents and warrants to American, the Escrow Agent, the Pass Through Trustee and the Paying Agent that:

(a) it is a société anonyme duly organized and validly existing in good standing under the laws of France and is duly qualified to conduct banking business in the State of New York;

SECTION 19. Security Procedures. With respect to all funds transfer instructions that are given by the Escrow Agent pursuant to this Agreement (other than those given in writing at the time of execution of this Agreement), whether in writing, by facsimile or otherwise, the Depositary is authorized to seek confirmation of such instructions by telephone call-back to the person or persons listed in the certificate of the Escrow Agent described in Section 8 hereof, and the Depositary may rely upon the confirmation of anyone purporting to be the person or persons so listed. If the Depositary is unable to contact any of the authorized representatives listed in such certificate, the Depositary may seek confirmation of such instructions by telephone call-back to any one or more of Escrow Agent’s executive officers (“Executive Officers”), as the case may be, which shall include the titles of Assistant Vice President or Vice President, as the Depositary may select. Upon written request from the Depositary, such “Executive Officer” shall deliver to the Depositary a fully executed incumbency certificate, and the Depositary may rely upon the confirmation of anyone purporting to be any such officer. The Escrow Agent acknowledges that these security procedures are commercially reasonable.
